Some fasting apps charge many times more. WaterFast is a fraction of that — with a 3-day free trial on every plan. You decide. FASTING APPS HAVE A PROBLEM They're either overpriced, bloated with social feeds and AI coaching you never asked for — or they're simple but their Apple Watch app runs a separate countdown that drifts out of sync with your iPhone. Two timers for the same fast. Not optimal. WATERFAST IS DIFFERENT One timer. One source of truth. Your Watch doesn't follow your iPhone — it leads. Start, monitor and end your fast right from your wrist, even with your iPhone in your pocket. When you pick it up, everything matches. Always. To the second. TRY IT ALL FREE FOR 3 DAYS Start a 3-day free trial and unlock everything — no strings attached. Then keep it monthly, yearly, or one-time lifetime. Cancel anytime. EVERYTHING INCLUDED • Every plan: 16:8, 18:6, 20:4, OMAD, 5:2 and fully custom • Start & stop fasts from Apple Watch — it leads, iPhone follows • Live timer with progress ring and fasting zones • Streak calendar — don't break the chain, unlimited history • All Apple Watch complications (circular, corner, inline, rectangular) • Hydration tracking with one-tap logging and daily goal • Full stats: current streak, longest fast, total hours, success rate • Export your data as CSV • No account required BUILT FOR APPLE WATCH — REALLY Most fasting apps treat the Watch as an afterthought. WaterFast was designed wrist-first. The timer state lives in one shared place: start a fast on your Watch during dinner, check the zone on your iPhone the next morning — same fast, same seconds, zero drift. KNOW YOUR FASTING ZONES Track exactly what's happening in your body — from digestion through fat burning and ketosis to autophagy. Each zone explained in plain language, with science-based hour ranges. Educational reference only — not medical advice. HYDRATION, ON YOUR WRIST Log a glass of water with one tap on your Watch, with haptic confirmation, synced instantly to your iPhone and Apple Health. A PRICE THAT RESPECTS YOU WaterFast PRO: monthly, yearly, or one-time lifetime. Every plan starts with a 3-day free trial. We think a fasting timer shouldn't cost more than your streaming service. PRIVATE BY DESIGN No account. No ads. No tracking. Your fasting and hydration data never leaves your device (except to your own Apple Health, if you choose). Start your 3-day free trial and run your first fast in under a minute. --- Medical disclaimer: WaterFast provides educational information about fasting. It is not medical advice. Consult your healthcare provider before starting any fasting protocol, especially if you have a medical condition, are pregnant, or take medication. --- Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
